MOD EDIT
- Please refrain from making wide generalizations about people who practice homebrew.
- Encouraging piracy is against the ToS. Do not state that is is fine to pirate video games in any way.

Thank you for your cooperation.


From https://gbatemp.net/threads/arbitrary-code-execution-on-4-x.496799/

The ReSwitched Hacking Team has done it again. Motezazer, KtemkinTrustZone and SciresM have achieved code execution on 4.x via deja vu at TrustZone level. This means devices on 4.x will be able to gain access to the whole system. SciresM strongly advises to not update in the future.

After less than a year, the Switch hacking team has moved extremely fast and now have got full access on the latest version. The progress being made is incredible, and in comparison, the 3DS took around 2 years to get ARM9 access. The scene is looking very promising so far and we are very lucky to have such talented people working on the Switch.

If you are on 4.x or below, you will be able to gain access to the whole system. Users on lower firmwares will get CFW first.

Whats the current switch firmware revision anyways? Haven't turned mine on in a couple of weeks, I should probably turn off auto update system and all that jazz. On the other hand, I only buy a few games for my switch anyways and I'd like to play online when they bring their services up so probably easiest just to keep updating and maybe buy a second switch down the road when they crack the system wide open.

God, I hope homebrews are going to be a thing soon so it can become the ultimate emulator machine it should have been. We could even see GC emulation happening.

It's already happening officially.
You mean the ports of Wii games for the chinese Shield market? Emulation is a whole another beast, and you can't compare Android's version of Dolphin running on a X1 Shield because Switch's CPU is significantly downclocked even in docked mode comparred to it.

Give me a reason for Nintendo to get Dolphin running on Chinese hardware that's stupidly similar to their own version of the same chip?

I actually have a spare Switch for eventual homebrew use. It’s currently on 2.3 or so. Should I update to the current firmware or leave it where it is?

Always stay on the lowest firmware, don't update

You should do your research on the X1 CPU in the SHIELD. There is a reason why Nintendo chose those clocks.

Can't wait to preserve only the biggest and best games that'll sell millions on the system the day it comes out that will for some indescribable reason will be hard to find in 2 years at least that's what I'm saying will happen as an excuse. People will appreciate my preservation of history and find me in my moral right to do so!

Please don't let this turn the Switch into an eventual PSP 2.0.
Hmm, though what about games that refuse to run on anything less than the current firmware and come packed with a forced-update for the firmware when ran?

I know that was a thing with the Xbox 360, and apparently for the PS4 too.

But yeah man, I really don't want the Switch to go the way of the PirateStationPortable. System was basically cut short in the west because the industry collectively decided to stop localizing PSP games because of piracy.

Isn't there a rule against turning homebrew threads into whining about piracy? I'm pretty sure gaf had one to prevent it from turning into a shitshow and then getting closed.

Is this something Nintendo can’t fix with a firmware update? I’d rather not have this happen so early in a system’s lifetime.
